STOP AND WASTE COCK.

SPECIFICATION forming part of Letters Patent No. 781,734, dated February '7, 1905.

Application filed August 27, 1904. Serial No. 222,409.

To It?! 'wiz/om, it m04/ concern:

Be it known that we, OHARLEY S. Mook and BuuNAuD H. JANSEN, citizens ot' the United States, residing' at Cleveland, in the county of Cuyahoga and State ot' Ohio, have invented certain new and useful Improvements in Stop and vWaste Cocks; and we do declare that the following is a full, clear, and exact description ot' the invention, which will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to stop and waste cocks; and the invention comprises means to conline the plug' within the body of the cock and to change the direction of rotation ofthe plug to provide either a right or a left stop and waste cock, all substantially as shown and described, and particularly pointed out in the claim.

.In the accompanying drawings, Figure 1 is a side elevation of our improved stop and waste cock and partly sectioned to disclose the construction and relation of parts. Fig. 2 is a plan view in horizontal section on line n: fr, Fig. l, and Fig. 3 is a horizontal section on line 1/ y, Fig. 1, with the stops arranged to provide a waste from the le't't. Fig. A is a perspective view ot' the screw confining cap for the plug. Fig. 5 is a perspective viewotl the neck portion ot' the coupling-body, and Fig. 6 is a perspective view oi' cap-inclosing band. Fig. T is a perspective view ofthe plug alone.

A represents the coupling-body with the valve or plug B set therein and adapted to operate as usual without being set, as required. Plug B also has the usual passage 2 and waste-passage 3, and a corresponding waste-hole 4 is provided in body A. These are common `features in all devices of this kind, but are incident to and cooperate with the novel features of our invention.

Body A in our device has a threaded neck which is provided with lug's 5 and 6, extending upwardly lfrom its upper edge and arranged substantially ninety degrees apart. Plug B is tapering and rests in the tapering seat or' the body and has its lower portion Hush with the face oll the lower portion A of the body. Plug B is provided at its upper end with an integral flange or collar 7), which flange or collar is above and removed from lugs 5 and G. An extension B ot' plug' B projects above said collar, and a square opening' is provided centrally within the plug' through said extension Afor the removable handle O.

A screw-cap l) is tlu'eaded to engage the threaded neck (l and has an inturned iiange I snugly fitting around extension B and bearing' down upon collar to hold plug B to its seat within body A. Said cap also serves as a sand-cap to prevent dirt from entering said valve-seat. To make the valve-plug reversible, so that the waste-opening can be brought to either right or left sides, we provide a screwstop 8, which is adapted to be screwed within either ot' the two openings 9 or l0. Cap l) has a slot or opening' in its side which comes opposite said screw-holes'between lugs 5 and 6, and screw-stop 8 can be engaged by a screw-driver through said slot or opening and transferred from one opening to the other when desired. \Ve prefer to use also a thin circular band or ring E, which rests snugly around the sides of said cap to close opening al against the admission ol dirt, and this band or ring of course requires removal before changing the screw-stop.

This stop and waste cock is especially well adapted Vfor high-pressure service, as the cap and flange on the plug' engage the cap to securely hold the plug' to its seat. The plug is heaviest at its upper end, and the cap engages the body and the plug' where it is best adapted to stand the greatest strain.

The stop and waste cock thus described is more cheaply constructed, more durable, and the parts more readily released and removed when necessary without damage to any of the parts than the old-style cocks. ',lhis is of special value in cocks that have been in use and require attention, especially after long service, and whenthc plug has become lixcd in its seat it is practically impossible to rotate it without releasing the plug in some way. Our screw-cap serves not only to hold the plug in its place, but provides for adjustment and release as well and also serves to act as a sand-cap and as a protecting inclosing casing 'for the stop members.

The lower end ot' plug B exposes a broad IOO Het surface at the bottom of the cock and provides :L safe and Convenient means for tapping' by hammer or other instrument to drive the plugl free from its seat if set and otherwise difioult ofremoval.

/Vhat We claim is- In a stop and Waste cook, a body having a central water-passage and a waste-passage at one side, a screw-threaded extension upon said body and a tapered valve-seat through said body, a tapering plug-valve in said seat provided with a Water-passage and an annular shoulder at the top of said pug, a set of stops on Said body and said plug` beneath said shoulder, a screw-cap to engage the I5 threaded extension of said plug and said shoulder' adapted to hold said plug' to its Seat and providinga chamber for inolosing Said stops, an opening at one Side or' said cap, and a member for sealing said opening.

1n testimony whereof We sign this Specification in the presence of' two Witnesses.
